It'll work (since like you say, the Windows clients wont see the old box 
again). I'm assuming you're switching names when doing the DNS "re-direct" to 
the new server. In that case, you could end up with having a Windows client 
needing a restore of a file which havent been exported yet. That could put you 
in the situation you're describing (Windows clients vs named-changed TSM 
server) since you'll have to redirect the restore to the old TSM server (since 
it's the only TSM server holding the actual file).

While we didn't do the hybrid method, I don't see any reason why that
wouldn't work.  As long as the windows boxes aren't connecting back up,
you should be good.

Subject: [ADSM-L] Question about "Hybrid" method upgrade to TSM V6.2.2
and server-to-server export

I am planning to do some upgrades using the "hybrid" method.
The V5.5 server will be shut down, the DB extracted, and the V5.5 server
will be brought back up and clients will run backups while we load the
DB into 6.2.

Then the V5.5 server will be disabled for client sessions, and an
incremental export/import used to get the backup inventory in sync with
6.2, then clients will be cut over to the 6.2 server via a DNS change.

Here's the question:

The description of the "hybrid" method assumes that you will do the
incremental export to media.  I'd rather use server-to-server.

I can't set up the server-to-server communication while the server names
(the TSM server name, not the host name) are the same.  Any reason I
can't get around that by doing a SET SERVERNAME V55SERVERNAME_OLD on the
V55 server, once all client sessions are cancelled?  I know that causes
havoc with Windows clients, but they should never be connecting to the
old server again.

Any suggestions/anybody tried this?

Thanks
W
